A+B+C=43 and A+B-C=17
\(\Rightarrow A+B=\frac{43+17}{2}\)
\(\Rightarrow A+B=30\)
\(\Rightarrow\frac{A+B}{2}=\frac{30}{2}=15\)
=> The average of A and B is 15
If A+ B = 7 , A - C = 3 then the average of B and C is
if A + B = 7, A - C = 3 then the average of B and C is .......................................
If A - B = 8 and the average of A and B is 7 then A = ........
( có ai biết cách giải thì làm hộ mình nha!)
The average of A ,B and C is 70 . The value of A is 2 more than B . The value of B is in more than C. Find value A , B and C
If the average of A and 6 is 10, then A =
if a+b =279, a < b and there are 16 odd numbers between a and b . Then the value of a is
the average of A,B,C is 48 and A is 8 less than the sum of B and C. The value of A is........
giúp tui nhé! cám ơn !
If M+N+P=49 and M-N+P=27 then the average of P and M is ...
If the average of y:y + 2 and y + 4 is 12.Then y =
